Application filed' iebruary 11, 1918. Serial No. 77,735.

. To all whom it may Conga y'a I Be known that WALTER Box, a: cit1-' zen of the United States, and a resident of Georgetown, in the county of Williamson and State of Texas, have invented a certain new and useful Improvement in Internal- Combustion Engines, of which the following is a specification. l

My -'nvention relates to internal combustion engines, and it consists in the combinations, constructions, and arrangements herein described and claimed. An object of my invention is to provide an engine having a rotary valve adapted to be continuously driven in one direction and so arranged thata charge will be drawn in, ignited, and exhausted in regular sequence, thereby driving the engine continuously.

In the drawings: Figure 1 isa vertical section through the cylinder of an engine provided with the improved valve. 'Fig. 2 is a top plan view of the valve with parts r in section. Fig. 3 is a view at right angles toFig. 2. Figs. 1 and 5 are sections on the lines 1- 1 and 5 5 respectively, of Fig.- 2. Fig. 6is a diagrammatic view showing the valve in exhaust position. Fig. 7 is a similar view showing the valve in inlet position. Fig. 8 is a central longitudinal sectional view through the device. Fig. 9-

is a bottom view of the cylinder head. Fig.

- 10 is a view of a portion of a modified form of the device. I

In carrying out my invention, I provide a cylinder 1 having a piston 2, which is connected with the crank 3 of the crankshaft 4, by means of the piston rod 5, and

the cylinder .is jacketed at the outer end as indicated at 6. The intake port 7 of the cylinder and the exhaust 8 open from 0p: posits sides of the cylinder lnto a common cylindrical valve chamber 9 formed in the cylinder head and from which leads a port or passage 10 into the cylinder. The valve is a cylindrical body 11 having solid ends and chambered intermediate its ends. At.

1 one end the valve is provided with an external gear ring 12 for engagement by suitable operating mechanism to rotate the valve and at the inner end of each ofthe solid portions thevalve has external annular grooves 13 for receiving packing rings 14. Between the packing ringsthe valve is chambered. At the end of the chambered portion remote from the ring 12, the. valve is cut away at opposite sides to form ports or passages 15 communicating with the chambered interior oftne valve. At the opposite end of the chambered portion the valve has. a port or passage 16, and the said port or passage is of much lcss'width than the passages 15 and communicates with the chamber of the valve and has its long axis in alinement with the long axis of the adjacent passage 15. From each side of the port or passage 16 the valve is recessed on its outer face as indicated at 17 over a depth suflicient to receive a'packing ring 18, the said ring being a split ring andextending from near oneside edge of the port or-pas- Patented Jan. 16, 1917.

port or passage 10 is designed to communicate by'means ofthe cylindrical chambered portion 9 of the valve with the intake 7 and. the exhaust 8' through the ports 15.

The latter are designed to register with the combustion chamber of the engine and with the spark plug 19 whereby the "interior of the valve constitutes in fact a part of the combustion chamber.

It will be understood that the intake and the exhaust are oilset with respect to the combustion chamber and that the enter- 1 ing charge passes by way' of the port 7 through the port 16 to the interior of the valve and the ports 15 permit the spark plug to ignite the charge within the valve and cylinder. v The valve is of a length to extend entirely through the cylinder head, and theend carrying the gear 12 may be provided with a fan to cool the motor.

In use, when the valve is in the position of.

Fig. 7, the charge may enter by way of the port 7, the port 16, and by way of the chambered interior of the valve, and the ports 15 byway of the port 10 to the cylinder. At the proper time the chartgawill be ignited by the spark plug 19 at the-time the ports 15 register with the spark plug and with the port 10. A. further movement of the valve will bring the port 16 in register with the exhaust 8 as indicated in Fig. 6, and the products of combustion may pass outby way of the ports 15 and 16. The ports 15 are of such size that the said ports will lap or register with the port'lO, while the port 16 is in register with the port 7 or 8. The port 16 is of the same width as the ports 7 and. 8 and during the explosion of the charge, the said port is out of register with both ports 7 and 8. lVhenever the port 16 is in register with the intake, packing ring 18 will be over the exhaust port and whenever the port 16 registers with the exhaust, the said )acking ring will be over the intake; at the time of explosion said ring will cover both the intake and the exhaust. In a multicylinder engine, it will be understood that there will be a section of the valve for 10 each cylinder, but will all be made in one piece.

It will be understood that the valve through the gear ring 12 is connected to a moving part of the engine, to cause the valve 15 to rotate one half the crank shaft speed, and

both crankishaft and valve rotate in the direction of the arrows shown adjacent to the same, that is, clockwise. When the spark plug is removed, one may lookdirectly into the combustion chamber.

At each side of the ring 18 there is a small pin, these pins being used for pulling .the ring. They may be placed anywhere on the ring. The clutches must be placed on the edge as shown.

In- Fig. 8 I have shown a modified form of the device, in which a sleeve 20 may be inserted in the cylinder head to form a bushing or bearing for the rotatable valve.

It may be that the builder of the engine wants to use a metal that is not suitable for a bearing, and in such case he may insert the sleeve and finish it ed on the inside so that the valve will rotate within the sleeve.

This sleeve is provided with ports 21 and 22 arranged to register with the intake and exhaustports respectively, while the opening 23 registers with the passage 15 in the valve. It will be seen that in this form of the device a sleeve merely forms a suitable bearing for the valve, where the body portion of the engine itself can not so be used. I claim 1. In combination with the cylinder of an internal combustion engine having a substantially cylindrical valve chamber at the outer end thereof and extending transversely thereof,- sraid cylinder having a port open- :into'th combustion chamber and a c l- 30 in er having alined oppositely extending inlet and exhaust ports at the-valve chamber and at right an les to the port leading to the cylinder and 0 set longitudinally with respect to the first named port and having 5 niting mechanism at the opposite side of the chamber from the'first named port, of a rotary jvalve in the chamber and extending at its ends be ond the said chamber and having at one'fen a gear ring for connecting with n eansffor rotating the valve continuously in one direction, the ends .of the valve being. solid iind the intermediate portion being chambered, said valve having annular ,acking' grooves at the inner ends of 'the solid portions, and packing rings in the grooves,
